Official Act Math Thread June 2013

<p>SgtGutter is correct. By Debater1996’s logic, a rational number is simply one that can be written as the quotient of any fraction x/y. We can indeed write .34 (with a repeating 4) as the quotient of a fraction.</p>

<p>Let x= .344444
10x= 3.44444
1000x= 344.444
1000x-10x= 344.444-3.44444= 341
341/990 or 31/90 is the fraction of .34 repeating.</p>

<p>It was implied that all of the choices were rational (it said someone along the lines of “of all the following rational numbers…”). You were over thinking the question.</p>

<p>Not by Debater’s logic, but if you even look up the definition of rational numbers, it includes any numbers that repeat.</p>

<p>1.132435465768798013243546576879801324354657687980… is still rational because 1324354657687980 repeats. By definition, there is one quotient that produces the results.</p>

<p>^agreed. I was simply trying to show that even using Debator’s flawed logic, .34 repeating could be put into fraction form.</p>

<p>Wait, one of them was .43 repeating? That’d make sense why I didn’t put it. I must have overlooked it and thought that it also said .44.</p>

<p>it was .34 repeating, .343434343434343434343434343434</p>

<p>Still, I must have gone quickly, and not thought about it. Oh well. I’m assuming that this curve will be generous (based on the general reaction to the math test), and since this is the only one that I have confirmed is wrong, there is no need to worry. </p>

<p>But that does make sense, though. Since I thought that they were the same, I must have assumed that the repeating wouldn’t work, so I just put the next highest.</p>

<p>ugh… that makes sense. totally dropped the ball on definition of rational. i thought i’d avoided a trick question here, but not to be…</p>

<p>Do we all agree d=130 was the answer?</p>

<p>Which question was that one relativelysmart?</p>

<p>“Which statement would give the most accurate way of solving the triangle” or something along those lines.</p>

<p>For English, was it that account for or that accounts for? And was it adorn?</p>

<p>This isn’t the English thread, buddy.</p>

<p>I agree that d=130 was the answer</p>

<p>@relativelysmart I also got d=130</p>

<p>I’m pretty confused for all the arguing about the Ferris Wheel one, but wasn’t in the straight line one because velocity was constant?</p>

<p>Doesn’t matter if velocity is constant, the height of the Ferris wheel will still always model a sinusoidal graph. I distinctly remember doing problems involving the height of a Ferris wheel with a sinusoidal curve in trig class.</p>

<p>Lol I know, but I don’t know where the English thread is?</p>

<p>Do you think that there is a chance -1 on Math could be a 36?</p>

<p>^ a chance? Absolutely. The October ACT’s math curve was extremely generous. I scored a 34 with a -5 for sure. There’s always the possibility.</p>

<p>@CHS2014189 The sinusoidal started down right? There were two of them, one started by going up and the other went down</p>
